As informações da bateria não são exibidas corretamente no ubuntu 16.04.1

Question

Eu fiz uma nova instalação do Ubuntu 16.04.1 em um laptop asus x556uak e notei que quando conectado a AC e a bateria não está carregando o sistema mostra o ícone da bateria como descarregando, mas quando a bateria descarregou um pouco e quando conectado novamente carrega, então o sistema mostra o ícone da bateria como conectado a AC e carregamento.

Também notei que apesar de eu ter 2 38 Whr células o ubuntu está detectando apenas uma célula de 38 Wh, como se a segunda não existisse? Mas talvez isso não seja um bug e mude para bateria secundária quando o primeiro estiver vazio?

Esta é a saída de upower -d

Eu atualizarei e postarei a saída de upower -d quando a bateria estiver cheia e conectada a AC.

Obrigado pelo seu tempo.

UPDATE

Esta é a saída de upower -d quando a bateria já está carregada e o laptop está conectado ao AC:
